About Area & Land Converter
Area measurement units scale with the square of linear dimensions (e.g., doubling side length increases area by 4×).
This converter supports everyday floor plan metrics (square feet, square meters), agricultural/real estate measures (acres, hectares), and regional geographic metrics (square miles, square kilometers).

Background
Area units scale with the square of length. Everything is converted through square meters using exact definitions: 1 hectare = 10,000 m2, 1 ft2 = 0.09290304 m2, 1 acre = 4,046.8564224 m2.
This is why doubling the side of a square quadruples its area, and why a conversion factor for area is the square of the matching length factor.
Common mistakes
- Using a length factor on an area. Feet to meters is 0.3048, but square feet to square meters is 0.3048 squared, about 0.0929.
- Mixing the US survey acre with the international acre for legal land measurements. They differ by a tiny fraction.
- Confusing acres with hectares. One hectare is about 2.47 acres.
